Paper Abstract

In this paper, we present results concerning the fabrication and characterization of glass-ceramics based on chalcohalide for application as laser host materials. The objective is to develop a highly efficient host material for rare-earth doping. The studied system is Ga-Ge-S-CsCl with Er3+ ions as doping elements. Glass-ceramics have been prepared by thermal treatment of the base glass. The evolution of the optical transmission versus annealing time and temperature has been investigated. Preliminary up-conversion measurement of Er3+ were performed. Glass ceramics show higher luminescence efficiency as compared to the base glass. Nano-crystalline phases have been generated in well-controlled experimental conditions, so that crystals with reproducible size smaller than 50 nm could be achieved.
